Pierce was standing on his prideful soapbox plugging AGT, saying how they strive to find the best talent in the country, and no other show has this quality of acts, yada yada yada, when Lauren stopped him in his tracks.

Lauren told Piers that she had auditioned for “America’s Got Talent” on TWO separate occasions and never even made it past the screening and never got to sing for the judges.

Morgan seemed horrified, or at least as horrified as his smugly little brain will allow, and joked that he was going to call the producers as soon as he left Jay’s taping.

It was classic. And it was fun to see a 16-year-old girl put the big fat sellout Piers Morgan in his place.

Kudos Lauren!

In addition to embarrassing Piers, Lauren also talked to Jay about her relationship with American Idol winner Scotty McCreery.

Lauren says they are NOT a couple and are NOT involved in any way other than with preparing for the Idol summer tour starting next month.

Hmmm, we don’t believe it. The two seem like perfect lovebirds and we hope their friendship blossoms.

If the two need some advice on how to do things up right and let the world see their public displays of affection, they can just ask Justin Bieber and Selena Gomez for advice – because this Royal Couple have the PDA system down to a science.
